Solitary Massive Right Ventricular Metastasis of Renal Cell Carcinoma Without Inferior Vena Cava or Right Atrium Involvement

Abstract

Right ventricular metastases from renal cell carcinoma without inferior vena cava or right atrium involvement are rare. A 67-year-old male presented with hematuria and congestive heart failure. Computed tomography revealed a left renal mass. In addition, an intra-cardiac mass was found during the preoperative workup, causing right ventricular outflow tract obstruction. His past medical history included previous coronary bypass grafting. The patient underwent combined radical nephrectomy and removal of right ventricular mass. Pathology confirmed renal cell carcinoma with extensive sarcomatoid features in both the left kidney and right ventricle. His postoperative recovery was unremarkable.
